manganese, strontium, lead, copper, zinc, nickel, chromium, ca(iium, 

 lithium, and silver. Most of these elements are rarely detected in 

 water samples from other areas. Groundwater samples commonly contain 

 more than Z5, 000 milligrams per liter (mg/1) total dissolved solids (TDS) 

 with some exceeding 50,000 mg/1 TDS, which is more saline than sea 

 water (36,000 mg/1 TDS).
